   Yes:
       CREATE RULE rule_name AS ON INSERT TO table1       DO INSTEAD (           INSERT INTO table2 VALUES
(new.value1,new.value2);          INSERT INTO table3 VALUES           (x,y);       );
 
   You just omitted the parens and semicoli :-)

   Triggers  too  (even if yes above and effectively you haven't   asked for):
       CREATE FUNCTION whatever () RETURNS opaque AS '       BEGIN           INSERT INTO table2 VALUES
(new.value1,new.value2);          INSERT INTO table3 VALUES           (...);           RETURN NULL; -- returning NULL
froma BEFORE trigger                        -- suppresses the triggering INSERT to                        -- happen.
  END;'       LANGUAGE 'plpgsql';
 
       CREATE TRIGGER table1_ins BEFORE INSERT ON table1           FOR EACH ROW EXECUTE whatever();
